摘要
网格技术将处于不同管理域内的异构资源有效地聚合在一起,为各种大规模高性能网格应用提供了通用的基础支撑环境。为网格应用提供端到端QoS保证逐渐成为关注的焦点。文章介绍了网格应用的QoS要求,分析比较了GARA和G-QoSM两种网格QoS保证体系结构及主要特点,并探讨了端到端网格QoS的关键问题及相关技术。
Grid provides high-end applications with the ability to harness the power of large numbers of heterogeneous resources in different administration domains.More and more attentions are paid to research on end-to-end QoS for grid applications.Needs of QoS for grid applications are presented in this paper.Also two grid QoS architectures,namely GARA and G-QoSM,are introduced here associated with analysis of their characters.At last,key technologies of end-to-end grid QoS architecture are recommended in this paper.
